Ch.6 Vision. 1  Describe the characteristics of light and color, outline the anatomy of the eye and its connections with the brain, and describe the process of transduction of visual information. 2  Describe the coding of visual information by photoreceptors and ganglion cells in the retina. The photoreceptors form synapses with bipolar cells, neurons whose two arms connect the shallowest and deepest layers of the retina. 2  In turn, these neurons form synapses with the ganglion cells, neurons whose axons travel through the optic nerves (the second cranial nerves) and carry visual information into the brain.
The retina is a thin layer of tissue that lines the back of the eye on the inside. It is located near the optic nerve. The purpose of the retina is to receive light that the lens has focused, convert the light into neural signals, and send these signals on to the brain for visual recognition.The retina processes light through a layer of photoreceptor cells.These are essentially light-sensitive cells, responsible for detecting qualities such as color and light-intensity. The retina processes the information gathered by the photoreceptor cells and sends this information to the brain via the optic nerve.he purpose of the retina is to receive light that the lens has focused, convert the light into neural signals, and send these signals on to the brain for visual recognition.
